“Clean-coal”---Pre combustion

Some ideas before get into further:

---integrated gasification combined cycle (from thermo to chemical)

---expose coal to controlled amounts of O2 and high temperature steam

---coal breaks down without burning and energy is released as hydrocarbon converting to CO, H and other gases

---a products from electricity to hydrogen generated

More details on pre-combustion technology:

            Pre-combustion technologies involve removing CO2 before combustion the coal and the only product is hydrogen. Why we need hydrogen? Obviously that the hydrogen combustion does not emit any CO2 the only product is H2O and release heat at the same time.  The whole idea is to achieve a zero emission of CO2 goal in the future. Once there is less inputs of CO2, we can maintain the current CO2 level and prevent any worse situation will happen.

            The process consists of three stages. Methane or gasified coal that any kind of hydrocarbon fuel or mixture is injected into power plants and converted into CO that is the first step. And then, the shift conversion happens: let CO react with water and then we get CO2. At last, the carbon that contained in CO2 is separated from the hydrogen. The CO2 will be transferred to other places to store securely.
